When a car salesman says your loan is "only 2.5%", he means a flat rate โ not the true cost of borrowing. The effective interest rate (EIR) on a Malaysian hire purchase loan is roughly 1.8 to 1.9 times higher than the advertised flat rate. Here is what that means for your wallet.
What Is a Flat Rate in Hire Purchase?
In Malaysia, hire purchase (HP) loans use a flat rate system. Interest is calculated on the original loan amount for every year of the tenure โ not on the reducing balance. This makes it appear cheaper than it really is.
Total Interest = Principal x Flat Rate x Tenure (years)
Monthly Instalment = (Principal + Total Interest) / (Tenure x 12)
Flat Rate to Effective Rate Conversion Table
| Flat Rate | Effective Rate (approx) | Monthly Payment (RM80k, 7yr) |
|---|---|---|
| 1.5% | 2.8% | RM1,024 |
| 2.0% | 3.7% | RM1,057 |
| 2.5% | 4.7% | RM1,095 |
| 3.0% | 5.6% | RM1,133 |
| 3.5% | 6.5% | RM1,171 |
Why Banks Use Flat Rates
Banks quote flat rates because they look lower and are easier to calculate. Under the Hire Purchase Act 1967, lenders must disclose the flat rate โ but not necessarily the effective rate prominently. Always ask for the EIR before signing.

Flat Rate vs Reducing Balance โ Side by Side
Mortgage loans use a reducing balance method โ interest falls as you pay down principal. Hire purchase uses a flat rate, so you pay the same interest every month even as your balance shrinks. This is why refinancing an HP loan early often saves very little.
